Customers who purchase the Samsung Galaxy S3 or S4 on Sprint could get another one free.

The carrier is offering this new buy one get one free deal to existing customers and new lines that are eligible for promotion. The Sprint variant of the Galaxy S4 currently retails for $199.99 while the Galaxy S3 sells for $99.99.

Sprint offers the S4 in white and black with purple coming soon and the S3 in white, blue and purple. The carrier is labeling this its BOGO sale. There is no word on how long it will last.

A Galaxy S4 Autumn Brown model could be released sometime in the near future.

A new picture was leaked this week that shows the device in the new color with Verizon branding. The image was posted by Evleaks. Judging from the photo, this could end up being an exclusive for the carrier.

The back of the model is black with a diamond shaped pattern. The front bezel features the new chocolate-like color. This version has not been introduced anywhere else, so Verizon might be the first company to carry it. It will be the third official Samsung Galaxy S4 color if it ends up being released.

It currently is available in Arctic Blue and Aurora red. The company is expected to release these new colors in the near future, according to a report from SamMobile.

The new version of the device has already become wildly popular in Korea, as it has sold over 150,000 units.

The Galaxy S4 LTE-A comes equipped with a Qualcomm Snapdragon 800 SoC instead of the Snapdragon 600 that is found in the international model. Other than that the specs on both versions are the same. Both models feature a 5-inch 1080p Super AMOLED Display, 2GB of RAM, a 13-megapixel rear camera, 32GB built-in memory, a microSD slot and an IR port.
